Capacity & Compatibility

This NEMIX RAM kit provides 64 GB of DDR5 memory in a two-module configuration. It is built for the Dell PowerEdge XR7620 rack server and uses registered ECC RDIMM modules that operate at 1.1 V.

Who This Suits

Administrators expanding a PowerEdge XR7620 with validated ECC registered memory will find this kit a direct fit. Buyers who need unbuffered UDIMM modules, a different pin count or non-ECC operation should look elsewhere.

Deciding Specification

The modules are 288-pin DDR5 RDIMMs rated at 4800 MT/s with CL40 latency and a 2Rx8 organisation. Confirm that your server requires registered ECC RDIMMs at this speed before ordering.

Questions about this item

Will this DDR5 4800 kit run reliably with the existing 32GB modules already in my PowerEdge XR7620?

This kit provides two 32GB registered ECC RDIMMs at 1.1V CL40; mixing ranks or speeds can prevent the server from posting, so Dell recommends populating all slots with identical modules.

How do I confirm the 64GB kit is detected and error-correction is active after installation?

Enter the system BIOS or iDRAC interface on the PowerEdge XR7620 — both will show 64GB total capacity, DDR5 4800 speed, and ECC status as enabled when the modules are seated correctly.

What exactly ships in the box and do I need any extra brackets or cables?

The package contains two 288-pin DDR5 RDIMM modules (2 x 32GB) only; no heat spreaders, brackets, cables or tools are included.
